EclipseAndTycho

Notes about setting up Triquetrum to use Eclipse Tycho.

Problem

We want to set up the Triquetrum Git Repo to use Eclipse Tycho for so that we can build Triquetrum from the command line.

Generate pom.xml files

The Eclipse Tycho Tutorial at Vogella.com is suggests that we do: 

  mvn org.eclipse.tycho:tycho-pomgenerator-plugin:generate-poms -DgroupId=triquetrum

This creates the pom.xml files

Dependency Problem

The tutorial suggests running: 

  mvn clean verify

The tutorial states:

"Tip: It is not recommended to use the mvn clean install command, instead you should use mvn clean verify. If you would use the install option, the build result would be installed in your local Maven repository and this can lead to build problems.

The tutorial states:

"Warning If you try to execute this POM file, the build fail because you have not yet configured your dependencies."

[$[Get Code]]

The org.eclipse.triquetrum.target.platform/target/plugins/ptolemy.core_11.0.0.201511291558.jar file has a META-INF/MANIFEST.MF that exports the ptolemy.data package.

So, we need to add these dependencies.

POM-less Tycho builds

Further reading finds POM-less Tycho builds.

Be sure that you have mvn 3.3 or later installed.

To use it, create .mvn/extensions.xml

<?xml version="1.0" encoding="UTF-8"?>
<extensions>
  <extension>
    <groupId>org.eclipse.tycho.extras</groupId>
    <artifactId>tycho-pomless</artifactId>
    <version>0.24.0</version>
  </extension>
</extensions>
[$[Get Code]]

Then remove the */pom.xml files.

Note that we have a pom.xml file that was created by Generate pom.xml files above.

Running mvn clean results in the same problem as above where we are depending on ptolemy.data.

Tycho Target Platform

    • In Eclipse, the triq.target has a definitions tab that lists the location of the ptII jar files:

triquetrumDeps

Jay Jay Billings suggested using something similar to https://github.com/jayjaybillings/ICEDeps

I've created https://github.com/cxbrooks/triquetrumDeps

To use it, be sure that you have mvn 3.3 or later installed, which is needed by POM-less Tycho builds. To check, run 

  mvn --version
git clone -b cxbrooks/eh/10/AddPom https://github.com/eclipse/triquetrum
git clone https://github.com/cxbrooks/triquetrumDeps
cd triquetrum
mvn -N install
